Have two USB Audio Device Class

CubeMX returns the information: The USB AUDIO share the same audio frequency

Cube tries to tell you : this is impossible, it cannot work.

 you want two steering wheels in one car.

so what you want to do with it ?

Thanks for your reply, but Cube does not tell me it is not possible.

There is also plenty of things that can be done outside of Cube (multiple class driver is one example) that is why I'm asking if there is actually something that prevents this implementation or a limitation that I might bypass with a custom implementation.

Unfortunately Cube does not support this "as is", but it can be fixed manually in the code.

Try to create two Cube projects, each one with one USB instance, then merge. (or two USB instances with different classes).

Pavel, thanks for your reply. Will definitly try this and let the community know.

I confirm this worked out just fine.
